SA20 - The ‘Studio Amp’ CUSTOM HIWATT 20 - Legendary Hiwatt Tone in a Smaller Package

From bright spanking clean through to rich creamy overdrive - this amp can do it all! The Hiwatt Custom 20
is ‘cathode biased’ (aka Class A) which adds a ‘touch sensitive’ feel to the amps response. With the addition
of a Gain Control you are able to drive the Custom 20 into an awesome natural overdrive without the
customary Hiwatt ‘loud’. Perfect for studio work and intimate venues.

Pedal friendly, compact and able to travel the world, this professional piece of gear is hand-built in the
Hiwatt Custom Shops England.
